Gina loaned Gerry $300 at an interest rate of 10 percent a year. How much interest will Gina get if Gerry pays Gina after 6 months

What’s the answer

1 answer

To calculate the interest Gina will receive for a loan of $300 at an interest rate of 10% per year for 6 months, you can use the formula for simple interest:

\[ \text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time} \]

Where:

  • Principal = $300
  • Rate = 10% per year (or 0.10 as a decimal)
  • Time = 6 months (which is \( \frac{6}{12} = 0.5 \) years)

Now, plug in the values:

\[ \text{Interest} = 300 \times 0.10 \times 0.5 \]

\[ \text{Interest} = 300 \times 0.05 \]

\[ \text{Interest} = 15 \]

So, Gina will get $15 in interest if Gerry pays her after 6 months.
